Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RP164PJ241CS is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 240 Ohm
• Tolerance: ±5%
• Number of resistor elements: 4
• Circuit configuration: Isolated
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 155°C
• Package type: 1206 (3216 Metric), Convex, Long Side Terminals
• Pin count: 8
• Mounting type: Surface Mount
• Physical dimensions: 0.126" L x 0.063" W (3.20mm x 1.60mm)

Allowable Variation:

• Power per element: Substitute parts may exceed the original 62.5mW specification, provided all other parameters remain identical. Higher power ratings ensure thermal margin and component reliability.

The RAVF164DJT240R from Stackpole Electronics Inc satisfies all mandatory parameters and provides increased power dissipation capability (100mW per element), making it a direct functional substitute.

Parameter Comparison

Engineering Selection Recommendations

The RAVF164DJT240R is a qualified substitute for the obsolete RP164PJ241CS based on the following engineering criteria:

Electrical Compatibility: Both parts maintain identical resistance value (240 Ohm), tolerance (±5%), temperature coefficient (±200ppm/°C), and operating temperature range (-55°C to 155°C). The RAVF164DJT240R provides enhanced power dissipation (100mW per element versus 62.5mW), which increases thermal headroom without compromising circuit performance.

Physical and Mechanical Compatibility: Package dimensions, pin configuration, and mounting type are identical. Both components use 1206 (3216 Metric) convex, long side terminal packages with 8-pin configurations suitable for surface mount assembly.

Regulatory and Compliance Status: Both parts are ROHS3 compliant and REACH unaffected. The RAVF164DJT240R carries AEC-Q200 automotive qualification, indicating enhanced reliability screening and process control.

Product Availability: The RP164PJ241CS is obsolete. The RAVF164DJT240R is active production status with documented inventory availability, ensuring long-term supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the RAVF164DJT240R be used as a direct replacement for the RP164PJ241CS in existing designs?

A: Yes. The RAVF164DJT240R is electrically and mechanically compatible with the RP164PJ241CS. All critical parameters—resistance, tolerance, temperature coefficient, operating range, package type, and pin configuration—are identical. The increased power rating (100mW versus 62.5mW per element) provides additional thermal margin and does not introduce compatibility issues.

Q: What is the significance of the higher power rating in the RAVF164DJT240R?

A: The RAVF164DJT240R is rated for 100mW per element compared to 62.5mW in the RP164PJ241CS. This higher rating indicates greater thermal dissipation capability and typically reflects more robust internal construction. In applications where the original part operated near its power limit, the substitute provides improved reliability and thermal performance.

Q: Are there any package or footprint differences between these parts?

A: No. Both parts use identical 1206 (3216 Metric) packages with convex, long side terminals. Physical dimensions (0.126" L x 0.063" W / 3.20mm x 1.60mm) and maximum seated height (0.024" / 0.60-0.61mm) are equivalent. PCB footprints and assembly processes require no modification.

Q: What is the difference between the RP series and RAVF series designations?

A: RP and RAVF are manufacturer-specific series designations. RP identifies Samsung Electro-Mechanics resistor arrays; RAVF identifies Stackpole Electronics Inc resistor arrays. Series designation does not affect electrical or mechanical compatibility when all specified parameters match.

Q: Does the AEC-Q200 qualification on the RAVF164DJT240R affect its use in non-automotive applications?

A: No. AEC-Q200 qualification indicates that the RAVF164DJT240R meets automotive-grade reliability and screening standards. This qualification is a superset of standard industrial requirements and does not restrict use in non-automotive applications. The part is suitable for any application requiring the specified electrical and thermal characteristics.

Q: What is the moisture sensitivity level, and why is it relevant?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity. These components do not require special moisture control during storage, handling, or assembly. Standard industrial storage conditions are acceptable.

Q: Are there any temperature coefficient or tolerance differences that would affect circuit performance?

A: No. Both parts maintain ±200ppm/°C temperature coefficient and ±5% tolerance across the -55°C to 155°C operating range. Temperature-dependent resistance drift and tolerance stack-up calculations remain identical for both parts.
