• Package format: 2512 (6432 Metric)
• Composition: Thick Film
• Number of terminations: 2
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Allowable Variations:

• Tolerance: ±5% or tighter (±1% acceptable)
• Power rating: Equal to or greater than 1.5W (2W acceptable)
• Manufacturer: TE Connectivity product lines
• Series designation: Different series within TE Connectivity portfolio

The substitute parts listed maintain electrical equivalence through identical resistance specifications and thermal operating characteristics.

Parameter Comparison

Engineering Selection Recommendations

CRGS2512J27R (Original Part)

Use this part when the original specification requires pulse withstanding capability and the 1.5W power rating is sufficient for the application. This part maintains active production status with standard RoHS compliance.

352127RFT (Substitute - Preferred for Automotive Applications)

This substitute provides tighter tolerance (±1% versus ±5%) and increased power rating (2W versus 1.5W). The part carries AEC-Q200 automotive qualification and ROHS3 compliance. Selection of this part is appropriate when automotive-grade reliability is required or when the tighter tolerance improves circuit performance. The MSL rating of 1 (Unlimited) indicates superior moisture handling characteristics.

CRGH2512J27R (Substitute - Direct Upgrade)

This substitute maintains the ±5% tolerance specification while providing increased power rating (2W versus 1.5W). The part is ROHS3 compliant with MSL rating of 1 (Unlimited). This option is suitable for applications where the original power rating is marginal or when design margin enhancement is desired without tolerance specification changes.

All three parts share identical resistance values, package geometry, thermal characteristics, and operating temperature ranges, ensuring functional equivalence in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can CRGS2512J27R be directly replaced with 352127RFT?

A: Yes. Both parts share identical 27 Ohm resistance, 2512 package format, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. The 352127RFT provides tighter tolerance (±1% versus ±5%) and higher power rating (2W versus 1.5W), making it a direct functional substitute. Dimensional compatibility is maintained within standard 2512 package tolerances.

Q: What is the difference between CRGS2512J27R and CRGH2512J27R?

A: Both parts are 27 Ohm ±5% thick film resistors in 2512 package format with identical thermal specifications. The primary difference is power rating: CRGS2512J27R is rated at 1.5W while CRGH2512J27R is rated at 2W. The CRGS series includes pulse withstanding features, while the CRGH series does not specify this feature. Both are ROHS3 compliant with MSL rating of 1 (Unlimited).

Q: Is the 352127RFT suitable for non-automotive applications?

A: Yes. The AEC-Q200 automotive qualification of 352127RFT indicates enhanced reliability and quality assurance. This part functions in any application requiring a 27 Ohm ±1% 2W thick film resistor in 2512 package format. The automotive qualification does not restrict use to automotive circuits.

Q: Are there dimensional compatibility concerns when substituting these parts?

A: Dimensional variations are minimal and within standard 2512 package tolerances. CRGS2512J27R measures 0.250" L x 0.126" W, 352127RFT measures 0.248" L x 0.126" W, and CRGH2512J27R measures 0.252" L x 0.126" W. All three parts have identical height specifications of 0.026" (0.65mm) and maintain standard 2512 footprint compatibility for PCB layout purposes.

Q: What does MSL rating of 1 (Unlimited) indicate?

A: MSL (Moisture Sensitivity Level) rating of 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. Parts with this rating do not require special moisture control during storage, handling, or assembly processes. The original CRGS2512J27R lists MSL as Not Applicable, while both substitute parts carry MSL 1 (Unlimited), providing superior moisture tolerance.

Q: Can tolerance differences affect circuit performance?

A: Tolerance differences between ±5% and ±1% affect circuit accuracy and stability. The 352127RFT with ±1% tolerance provides tighter resistance control, beneficial in precision applications such as signal conditioning, reference circuits, or current sensing. For general-purpose applications where ±5% tolerance is acceptable, either specification performs equivalently.

Q: What is the significance of ROHS3 compliance versus RoHS Compliant?

A: Both designations indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 represents the current version of the directive with updated substance restrictions. Parts marked as ROHS3 Compliant meet the latest regulatory requirements. The original CRGS2512J27R is RoHS Compliant, while substitute parts carry ROHS3 Compliant status, indicating alignment with current environmental standards.
