Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS3216F5231CS are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 5.23 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters (Must Match):

• Package type: 1206 (3216 Metric)
• Number of terminations: 2
• Composition: Thick Film

Compliance Parameters (Must Match):

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Unaffected status

All identified substitute parts meet these core requirements. Variations in physical dimensions (length, width, height) within the 1206 package specification and differences in additional features (such as automotive AEC-Q200 certification) do not prevent substitution but may offer enhanced capabilities for specific applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

CRCW12065K23FKEA (Vishay Dale) and RC1206FR-075K23L (YAGEO) are recommended as primary substitutes. Both parts maintain active product status and are in full production. CRCW12065K23FKEA includes automotive AEC-Q200 certification, which provides additional qualification for automotive applications. RC1206FR-075K23L offers moisture-resistant properties aligned with the original part specification.

Secondary Substitute (Legacy Status):

ERJ-8ENF5231V (Panasonic Electronic Components) is electrically and mechanically equivalent but carries a "Not For New Designs" product status. This part is suitable for replacement in existing applications or legacy system maintenance but should not be selected for new circuit designs.

Compliance Alignment:

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and MSL Level 1 rating, ensuring regulatory and environmental compatibility with the original RCS3216F5231CS specification.

Frequently Asked Questions (FAQ)

Q: Can CRCW12065K23FKEA replace RCS3216F5231CS in all applications?

A: Yes. CRCW12065K23FKEA meets all electrical and mechanical specifications of RCS3216F5231CS. The addition of AEC-Q200 automotive certification provides enhanced qualification for automotive environments without affecting general-purpose applications.

Q: What is the difference between the substitute parts?

A: All three substitutes (CRCW12065K23FKEA, ERJ-8ENF5231V, RC1206FR-075K23L) share identical electrical parameters (5.23 kOhms, ±1%, 0.25W) and package type (1206). Differences include manufacturer, product status, and optional certifications. CRCW12065K23FKEA includes AEC-Q200 automotive qualification. ERJ-8ENF5231V is marked "Not For New Designs." RC1206FR-075K23L emphasizes moisture-resistant properties.

Q: Are there physical dimension differences between these parts?

A: Minor variations exist within the 1206 package specification. Length ranges from 0.122" to 0.126", width is consistent at 0.063", and height ranges from 0.024" to 0.028". These variations remain within standard 1206 package tolerances and do not affect PCB footprint compatibility.

Q: Which substitute should be selected for new designs?

A: For new designs, select either CRCW12065K23FKEA or RC1206FR-075K23L, both with active product status. CRCW12065K23FKEA is preferred for automotive applications due to AEC-Q200 certification. Avoid ERJ-8ENF5231V for new designs due to its "Not For New Designs" status.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All substitute parts (CRCW12065K23FKEA, ERJ-8ENF5231V, RC1206FR-075K23L) are ROHS3 compliant with MSL Level 1 rating and REACH unaffected status, matching the original RCS3216F5231CS compliance profile.

Q: What is the impact of packaging format on substitution?

A: All substitute parts are supplied in Tape & Reel (TR) format, while the original part specification does not specify packaging format. Tape & Reel packaging is standard for automated assembly and does not affect electrical or mechanical compatibility. Verify tape specifications with your assembly process requirements if needed.
