Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 352012KJT is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Parameters:

• Resistance value: 12 kOhms
• Package / Case: 2512 (6432 Metric)
• Power rating: 1W
• Composition: Thick Film
• Packaging format: Tape & Reel (TR)
• RoHS compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameters:

• Tolerance: ±5% (direct equivalents) or ±1% (upgraded specification)
• Temperature Coefficient: ±200ppm/°C (standard) or ±100ppm/°C (upgraded specification)
• Operating Temperature Range: -55°C ~ 125°C (standard) or -55°C ~ 155°C (extended range)
• Product Status: Active or Not For New Designs
• Automotive qualification: Optional feature (AEC-Q200 rated parts are compatible)

Substitute parts are categorized as Direct Equivalents (matching all tolerance and temperature specifications), Upgrades (enhanced tolerance or temperature coefficient), or Similar (automotive-qualified alternatives with identical electrical specifications).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Selection (Identical Specifications):

The RMCF2512JT12K0 (Stackpole Electronics) and CRCW251212K0JNEG (Vishay Dale) are direct functional equivalents to the TE Connectivity 352012KJT. Both parts maintain identical electrical specifications (12 kOhms ±5%, 1W, ±200ppm/°C) and package format. Both are Active product status and ROHS3 compliant. The RMCF2512JT12K0 offers extended operating temperature range (-55°C ~ 155°C) and AEC-Q200 automotive qualification. The CRCW251212K0JNEG similarly provides extended temperature range and AEC-Q200 rating. Selection between these two should be based on supplier availability and inventory levels.

Upgraded Specification Selection (Enhanced Tolerance):

The ERJ-1TNF1202U (Panasonic) provides upgraded tolerance specification (±1% versus ±5%) and improved temperature coefficient (±100ppm/°C versus ±200ppm/°C). This part is suitable for applications requiring tighter resistance tolerance and improved thermal stability. Extended operating temperature range (-55°C ~ 155°C) and AEC-Q200 qualification are included. Product status is Not For New Designs; use only when existing designs require this specific part number or when tolerance upgrade is mandatory.

Legacy Product Consideration:

The ERJ-1TYJ123U (Panasonic) is functionally equivalent with extended temperature range and AEC-Q200 qualification but carries Not For New Designs status. This part is suitable only for sustaining production of existing designs or when legacy component compatibility is required.

Frequently Asked Questions (FAQ)

Q: Can the RMCF2512JT12K0 directly replace the TE Connectivity 352012KJT?

A: Yes. The RMCF2512JT12K0 is a direct functional equivalent. Both parts share identical resistance (12 kOhms), tolerance (±5%), power rating (1W), package (2512), and composition (thick film). The RMCF2512JT12K0 provides extended operating temperature range (-55°C ~ 155°C versus -55°C ~ 125°C) and AEC-Q200 automotive qualification, making it a compatible substitute without circuit redesign.

Q: What is the difference between the ERJ-1TNF1202U and the main part 352012KJT?

A: The ERJ-1TNF1202U is an upgraded specification variant. It maintains the same 12 kOhms resistance and 1W power rating but offers tighter tolerance (±1% versus ±5%) and improved temperature coefficient (±100ppm/°C versus ±200ppm/°C). Operating temperature range is extended to -55°C ~ 155°C. This part is suitable for precision applications requiring tighter resistance tolerance.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (ERJ-1TYJ123U, RMCF2512JT12K0, ERJ-1TNF1202U, CRCW251212K0JNEG) are ROHS3 compliant, matching the compliance status of the main part 352012KJT.

Q: What does "Not For New Designs" product status mean?

A: Parts marked "Not For New Designs" (ERJ-1TYJ123U, ERJ-1TNF1202U) are legacy components suitable for sustaining production of existing designs or replacement in fielded equipment. These parts should not be selected for new circuit designs. For new designs, select parts with Active product status: RMCF2512JT12K0 or CRCW251212K0JNEG.

Q: Do all substitute parts have the same physical dimensions?

A: All substitute parts use the 2512 (6432 Metric) package. Minor dimensional variations exist: TE Connectivity 352012KJT is 0.252" L x 0.126" W; RMCF2512JT12K0 is 0.248" L x 0.126" W; CRCW251212K0JNEG is 0.248" L x 0.124" W. All parts have identical height (0.028" maximum seated). These variations are within standard PCB footprint tolerances for 2512 package designs.

Q: Which substitute part offers the best thermal performance?

A: The ERJ-1TNF1202U offers the best thermal performance with temperature coefficient of ±100ppm/°C (versus ±200ppm/°C for other parts) and extended operating range to 155°C. However, this part carries Not For New Designs status. For new designs, RMCF2512JT12K0 and CRCW251212K0JNEG both provide ±200ppm/°C temperature coefficient with extended operating range to 155°C.

Q: Are automotive-qualified parts (AEC-Q200) necessary for this application?

A: AEC-Q200 qualification is optional and depends on application requirements. The main part 352012KJT does not carry AEC-Q200 rating. Substitute parts RMCF2512JT12K0, ERJ-1TYJ123U, ERJ-1TNF1202U, and CRCW251212K0JNEG all include AEC-Q200 qualification. Select AEC-Q200 rated parts only if automotive or high-reliability application standards mandate this certification.

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

A: All listed parts have Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity restrictions. These parts do not require special moisture control during storage, handling, or assembly. MSL 1 classification allows standard warehouse storage and manufacturing processes without desiccant packaging or baking requirements.
