MAX913CSA-T Equivalent & Substitute Parts

Part Overview

The MAX913CSA-T is a single-channel comparator with latch functionality manufactured by Analog Devices Inc./Maxim Integrated. This 8-SOIC surface-mount device provides complementary TTL output with integrated latch capability for signal comparison applications. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. Substitute parts must maintain electrical compatibility across supply voltage, input offset, bias current, output characteristics, and propagation delay specifications while accommodating packaging variations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Output Type: Complementary, TTL (required match)
• Supply Voltage Range: Must support 5V ~ 10V minimum
• Input Offset Voltage: Maximum 2mV @ ±5V (tighter tolerance preferred)
• Input Bias Current: Maximum 5µA @ ±5V
• Output Current: Minimum 20mA typical
• Quiescent Current: Maximum 10mA
• Propagation Delay: Maximum 14ns
• Package / Case: 8-SOIC or compatible surface-mount package
• RoHS3 Compliance: Required
• MSL Rating: 1 (Unlimited)

Substitution Categories:

1. Direct Equivalent (Same Package, Same Specifications): MAX913CSA+T — Identical electrical specifications with active product status and improved packaging options (Cut Tape & Digi-Reel).

2. General Purpose Comparators (Relaxed Type Specification): TL3116CD, TL3116CDR, TL3116ID, TL3116IDR — Texas Instruments general-purpose comparators with compatible electrical parameters. These parts feature slightly relaxed input offset voltage (3mV maximum) and support extended supply voltage ranges (±2.5V ~ 5V in addition to 5V ~ 10V). Package variations include 8-SOIC and 8-TSSOP options.

3. Package Variant (8-TSSOP): TL3116CPWR — Functionally equivalent to TL3116 series but in 8-TSSOP package (0.173", 4.40mm Width) for applications requiring alternative footprint compatibility.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): Select MAX913CSA+T when available. This part maintains identical electrical specifications to the MAX913CSA-T while offering active product status and improved packaging availability (Cut Tape & Digi-Reel). No design modifications are required.

For Extended Temperature Range Applications: TL3116IDR and TL3116ID support operating temperatures from -40°C to 85°C, compared to the MAX913CSA-T commercial range of 0°C to 70°C. These parts are suitable for industrial and automotive environments requiring wider temperature operation. TL3116IDR is currently active in production.

For Cost-Optimized Procurement: TL3116CD and TL3116CDR offer functional equivalence with general-purpose comparator architecture. Input bias current is significantly lower (1.1µA versus 5µA), and propagation delay is faster (12ns versus 14ns). Quiescent current is slightly elevated (14.7mA versus 10mA). These parts are suitable for applications where the latch function is not critical and general-purpose comparator performance is acceptable.

For Alternative Packaging: TL3116CPWR provides 8-TSSOP packaging (0.173", 4.40mm Width) as an alternative to 8-SOIC. This option accommodates space-constrained PCB layouts while maintaining electrical compatibility. Verify PCB footprint compatibility before selection.

Compliance Verification: All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) rating, ensuring compatibility with lead-free assembly processes and unlimited shelf life storage conditions.

Frequently Asked Questions (FAQ)

Q: Can MAX913CSA+T be used as a direct replacement for MAX913CSA-T? A: Yes. MAX913CSA+T is electrically and functionally identical to MAX913CSA-T with matching specifications across all critical parameters. The primary difference is product status (Active versus Obsolete) and packaging format (Cut Tape & Digi-Reel availability).

Q: What is the key difference between MAX913CSA-T and TL3116 series comparators? A: The MAX913CSA-T features integrated latch functionality, while TL3116 series are general-purpose comparators without latch capability. TL3116 parts have lower input bias current (1.1µA versus 5µA), faster propagation delay (12ns versus 14ns), and support extended supply voltage ranges (±2.5V ~ 5V in addition to 5V ~ 10V). Quiescent current is slightly higher in TL3116 variants.

Q: Are TL3116 comparators suitable for applications requiring latch functionality? A: TL3116 comparators do not include integrated latch functionality. Applications requiring output hold capability must implement external latch circuitry or select MAX913CSA+T for integrated latch operation.

Q: What is the difference between TL3116CD, TL3116CDR, TL3116ID, and TL3116IDR? A: TL3116CD and TL3116CDR operate over 0°C to 70°C commercial temperature range. TL3116ID and TL3116IDR operate over -40°C to 85°C industrial temperature range. CDR and IDR variants are currently active in production; CD and ID variants are obsolete or last-time-buy status. Electrical specifications are identical within each temperature grade.

Q: Can TL3116CPWR (8-TSSOP) be used in place of 8-SOIC packages? A: TL3116CPWR is electrically equivalent but uses 8-TSSOP packaging (0.173", 4.40mm Width) instead of 8-SOIC (0.154", 3.90mm Width). PCB footprint and land pattern must be verified for compatibility. Pin assignments remain identical.

Q: What are the compliance and certification differences between substitute parts? A: All listed substitute parts maintain ROHS3 compliance (lead-free, halogen-free) and MSL 1 (Unlimited) moisture sensitivity rating. REACH status is unaffected for all parts. ECCN classification is EAR99 for all variants. No compliance barriers exist for substitution.

Q: Which substitute part offers the best performance for high-speed applications? A: TL3116 series comparators provide faster propagation delay (12ns maximum) compared to MAX913CSA-T (14ns maximum). TL3116IDR and TL3116ID are recommended for timing-critical applications requiring maximum speed performance.

Q: Is inventory availability a factor in substitute part selection? A: Current inventory levels are provided for reference: MAX913CSA-T (3500 pcs), MAX913CSA+T (2900 pcs), TL3116CD (1429 pcs), TL3116CDR (3474 pcs), TL3116CPWR (1352 pcs), TL3116ID (3400 pcs), TL3116IDR (1541 pcs). Availability should be confirmed with suppliers for production requirements.
