Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters: resistance value (51 Ohm), tolerance (±5%), number of resistors (4), circuit type (isolated), number of pins (8), package type (1206 with concave long side terminals), mounting type (surface mount), and compliance certifications (ROHS3, REACH Unaffected, EAR99).

All substitute parts listed maintain these core electrical and mechanical specifications. Variations in power per element (62.5mW to 63mW), operating temperature range extensions, and physical dimensions within tolerance are acceptable for direct substitution. All substitute parts are active product status, providing improved availability compared to the obsolete main part.

Engineering Selection Recommendations

All listed substitute parts are functionally equivalent to CAT16-510J4GLF and maintain full compliance with ROHS3, REACH Unaffected, and EAR99 classifications. Selection among substitute parts should be based on product availability, packaging format requirements, and application-specific temperature range needs.

CAT16-510J4LF (Bourns) provides direct manufacturer continuity as an active product variant within the same CAT16 series, with identical electrical specifications and packaging.

742C083510JP (CTS Resistor Products) offers the highest inventory availability and is qualified for automotive AEC-Q200 applications.

EXB-V8V510JV (Panasonic Electronic Components) maintains identical electrical and thermal specifications with active product status.

TC164-JR-0751RL (YAGEO) extends the operating temperature range to -55°C ~ 155°C and includes automotive AEC-Q200 qualification, suitable for applications requiring enhanced thermal performance.

Frequently Asked Questions (FAQ)

Q: Can CAT16-510J4LF directly replace CAT16-510J4GLF?

A: Yes. Both parts share identical electrical specifications (51 Ohm ±5%, 4 isolated resistors, ±200ppm/°C), package type (1206 concave long side terminals), and compliance certifications. The primary difference is product status: CAT16-510J4LF is active while CAT16-510J4GLF is obsolete.

Q: What is the difference between the substitute parts?

A: All substitute parts maintain core electrical equivalence. Differences include manufacturer (Bourns, CTS, Panasonic, YAGEO), power per element rating (62.5mW or 63mW), operating temperature range (standard -55°C ~ 125°C or extended -55°C ~ 155°C for YAGEO), and application certifications (automotive AEC-Q200 for CTS and YAGEO variants).

Q: Are there packaging format differences among substitutes?

A: Yes. CAT16-510J4LF is supplied in Tape & Reel (TR) format. 742C083510JP is supplied in Cut Tape (CT) & Digi-Reel format. EXB-V8V510JV and TC164-JR-0751RL are supplied in Tape & Reel (TR) format. Verify packaging requirements for your procurement and assembly processes.

Q: Is TC164-JR-0751RL suitable for high-temperature applications?

A: TC164-JR-0751RL operates across -55°C ~ 155°C, extending 30°C above the standard range. This part is appropriate for applications requiring enhanced thermal performance within this extended range.

Q: Do all substitutes maintain the same physical dimensions?

A: All parts use 1206 (3216 Metric) package with concave long side terminals. Minor dimensional variations exist: CAT16-510J4GLF and CAT16-510J4LF measure 0.126" L x 0.061" W with 0.024" max height; 742C083510JP, EXB-V8V510JV, and TC164-JR-0751RL measure 0.126" L x 0.063" W with 0.028" max height. These variations remain within standard PCB footprint tolerances.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.
