MAX913MJA Equivalent & Substitute Parts

Part Overview

The MAX913MJA is a single-channel comparator with latch functionality, manufactured by Analog Devices Inc./Maxim Integrated. It features complementary TTL output and operates across a 5V to 10V supply range. The device is classified as obsolete, making equivalent and substitute parts necessary for ongoing production, maintenance, and new design implementations. Substitute parts must maintain functional equivalence in comparator operation, latch capability, and output characteristics while accommodating packaging and temperature range variations.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MAX913MJA is determined by the following critical parameters:

Functional Requirements:

• Single-channel comparator with latch functionality
• Complementary TTL output capability
• Supply voltage range: 5V ~ 10V

Electrical Performance Criteria:

• Input offset voltage: 2mV to 3mV maximum
• Input bias current: 1.1µA to 20µA maximum
• Output current: 20mA typical
• Propagation delay: 12ns to 16ns maximum
• CMRR: minimum 90dB

Package Compatibility:

• Through-hole or surface-mount packages acceptable
• 8-pin configurations (DIP, SOIC, TSSOP)

Compliance Considerations:

• RoHS3 compliance preferred for new designs
• Product status (Active vs. Obsolete) affects long-term availability

Substitute parts are grouped into two categories: direct replacements from Analog Devices (MAX913EPA+, LT1116CN8#PBF) and functionally equivalent alternatives from Texas Instruments (TL3116 series). All substitutes maintain the core comparator with latch architecture and TTL output characteristics required for functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: MAX913EPA+

The MAX913EPA+ is the manufacturer-recommended direct substitute for the MAX913MJA. It maintains identical electrical specifications (2mV input offset, 110dB CMRR, 14ns propagation delay) and preserves the latch functionality. The primary differences are extended operating temperature range (-40°C to 85°C versus 0°C to 70°C) and RoHS3 compliance. The 8-DIP through-hole package is mechanically compatible with the original 8-CDIP footprint. Product status is Active, ensuring long-term availability.

Secondary Recommendation: LT1116CN8#PBF

The LT1116CN8#PBF provides functional equivalence with slightly relaxed input offset specifications (3mV versus 2mV) and lower input bias current (20µA). It features CMOS output capability in addition to complementary TTL output. Operating temperature range matches the original (0°C to 70°C). RoHS3 compliance and Active product status support new design implementations. Quiescent current is elevated (38mA maximum), which may impact power-sensitive applications.

Tertiary Recommendation: TL3116IDR

The TL3116IDR from Texas Instruments offers functional equivalence in a surface-mount 8-SOIC package. It features superior propagation delay (12ns versus 14ns) and lower input bias current (1.1µA). Extended operating temperature range (-40°C to 85°C) and RoHS3 compliance support demanding applications. Product status is Active. Surface-mount implementation requires PCB redesign and assembly process modification.

Alternative Surface-Mount Option: TL3116CPW or TL3116IPW

Both parts provide identical electrical performance to TL3116IDR in 8-TSSOP packaging. TL3116IPW maintains Active product status with extended temperature range. TL3116CPW is Obsolete but offers higher inventory availability (888 units). Surface-mount packages reduce board space but require manufacturing process adaptation.

Compliance Consideration:

All recommended substitutes are RoHS3 compliant, addressing regulatory requirements for new production. The original MAX913MJA is RoHS non-compliant; substitution is necessary for compliance-mandated applications.

Frequently Asked Questions (FAQ)

Q: Can MAX913EPA+ directly replace MAX913MJA without PCB modification?

A: Yes. The MAX913EPA+ uses an 8-DIP through-hole package with 0.300" (7.62mm) spacing, mechanically compatible with the original 8-CDIP footprint. Electrical specifications are identical. No PCB redesign is required.

Q: What is the functional difference between "with Latch" and "General Purpose" comparators?

A: Comparators with latch functionality (MAX913MJA, MAX913EPA+, LT1116CN8#PBF) incorporate internal latching logic that holds the output state until reset. General Purpose comparators (TL3116 series) provide real-time comparison without latching. Application requirements determine which type is appropriate.

Q: Why do TL3116 parts show "General Purpose" type instead of "with Latch"?

A: TL3116 devices are general-purpose comparators without integrated latch functionality. They provide functional equivalence in comparator operation and TTL output characteristics but lack the latching feature. Applications requiring latching must use MAX913EPA+ or LT1116CN8#PBF.

Q: Is the extended temperature range of MAX913EPA+ (-40°C to 85°C) a concern for 0°C to 70°C applications?

A: No. Extended temperature range indicates broader operational capability and does not affect performance within the original 0°C to 70°C specification window. It provides additional margin for thermal stress and environmental variation.

Q: What are the packaging implications of switching from through-hole to surface-mount (TL3116 series)?

A: Surface-mount packages (SOIC, TSSOP) require PCB redesign with appropriate pad layouts, assembly process modification, and reflow soldering capability. Through-hole packages (DIP) use traditional wave soldering. Package selection depends on manufacturing infrastructure and board design constraints.

Q: Does the 3mV input offset of LT1116CN8#PBF versus 2mV of MAX913MJA affect circuit performance?

A: The 1mV difference falls within typical application tolerance margins for comparator circuits. Precision applications with tight hysteresis requirements should verify performance through simulation or prototype testing. For general-purpose threshold detection, the difference is negligible.

Q: Why is RoHS3 compliance important for substitute selection?

A: RoHS3 compliance is mandatory for products sold in regulated markets (EU, China, and others). Non-compliant components cannot be used in new production for these regions. All recommended substitutes are RoHS3 compliant, supporting global market access.

Q: Can TL3116IDR be used in applications originally designed for MAX913MJA?

A: Functionally, yes, with design considerations. TL3116IDR lacks integrated latch functionality, requiring external latching logic if needed. Surface-mount packaging necessitates PCB redesign. Electrical performance is superior (12ns propagation delay, 1.1µA input bias). Application-specific validation is required.

Q: What inventory status should influence substitute selection?

A: Active product status ensures long-term availability and manufacturing continuity. Obsolete parts carry discontinuation risk and may face supply constraints. For new designs or long-term production, Active status parts (MAX913EPA+, LT1116CN8#PBF, TL3116IDR) are preferred. Obsolete parts are acceptable for legacy system maintenance with limited production volumes.
