Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters: resistance value (3 kOhms), tolerance (±5%), package format (0402), composition (thick film), anti-sulfur feature, operating temperature range (-55°C ~ 155°C), and compliance certifications (ROHS3).

Substitute parts are grouped into two categories:

Direct Substitutes maintain identical electrical specifications and anti-sulfur construction. These parts are pin-compatible and functionally equivalent with no circuit redesign required.

Upgrade Substitutes provide enhanced specifications while maintaining the same package, resistance value, and operating temperature range. These parts feature higher power ratings (0.1W vs 0.063W) and/or tighter tolerance (±1% vs ±5%), offering improved performance margins in existing designs.

Parameter Comparison

Engineering Selection Recommendations

SFR01MZPJ302 is the primary direct substitute. Manufactured by Rohm Semiconductor, it maintains identical electrical and mechanical specifications to the TRR01MZPJ302 while offering active product status and AEC-Q200 automotive qualification. This part is recommended for direct replacement in existing designs without circuit modification.

AF0402JR-073KL (YAGEO) provides an alternative direct substitute with identical power rating and tolerance. This part features a lower temperature coefficient (±100ppm/°C vs ±200ppm/°C), which may provide improved stability in temperature-sensitive applications. AEC-Q200 certification is included.

ERJ-S02F3001X and ERJ-S02J302X (Panasonic Electronic Components) are upgrade substitutes offering higher power dissipation (0.1W vs 0.063W). ERJ-S02F3001X additionally provides tighter tolerance (±1%). Both parts maintain the same package and operating temperature range. These upgrades are suitable for designs requiring enhanced thermal margin or improved tolerance performance.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and anti-sulfur construction. Selection should be based on design requirements for power margin, tolerance precision, and automotive qualification needs.

Frequently Asked Questions (FAQ)

Q: Can SFR01MZPJ302 be used as a direct replacement for TRR01MZPJ302?

A: Yes. Both parts share identical resistance (3 kOhms), tolerance (±5%), power rating (0.063W), package (0402), and operating temperature range (-55°C ~ 155°C). SFR01MZPJ302 is the active equivalent with AEC-Q200 qualification.

Q: What is the difference between direct substitutes and upgrade substitutes?

A: Direct substitutes (SFR01MZPJ302, AF0402JR-073KL) maintain identical electrical specifications. Upgrade substitutes (ERJ-S02F3001X, ERJ-S02J302X) provide enhanced power ratings (0.1W) and/or tighter tolerance (±1%), requiring thermal and circuit analysis to confirm suitability.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All listed substitute parts carry AEC-Q200 automotive qualification. The original TRR01MZPJ302 does not include this certification.

Q: Does package size differ among substitutes?

A: No. All parts, including the main component and all substitutes, use the 0402 (1005 Metric) package with identical footprint dimensions (0.039" L x 0.020" W).

Q: Can ERJ-S02F3001X be used in place of TRR01MZPJ302 without design changes?

A: Yes, from a mechanical and thermal perspective. The higher power rating (0.1W vs 0.063W) and tighter tolerance (±1% vs ±5%) provide improved performance margins. No circuit redesign is required, though thermal analysis may confirm reduced operating stress.

Q: What is the temperature coefficient difference between AF0402JR-073KL and other substitutes?

A: AF0402JR-073KL has a temperature coefficient of ±100ppm/°C, compared to ±200ppm/°C for TRR01MZPJ302, SFR01MZPJ302, ERJ-S02F3001X, and ERJ-S02J302X. This lower coefficient provides improved resistance stability across the operating temperature range.
