Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 1676437-5 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Resistance value: 7.5 kOhms (exact match required)
• Package / Case: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Temperature Coefficient: ±10ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match or wider range acceptable)
• Number of Terminations: 2 (exact match required)

Allowable Variation Parameters:

• Tolerance: ±0.1% or tighter (±0.05% acceptable as upgrade)
• Power Rating: 0.1W or higher (0.125W acceptable as upgrade)
• Packaging format: Tape & Reel acceptable for equivalent function
• Manufacturer: Alternative qualified manufacturers acceptable
• Compliance certifications: ROHS3 and AEC-Q200 acceptable as enhancements

All identified substitute parts maintain the mandatory compatibility parameters while offering equal or enhanced electrical performance and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Manufacturer): RN73C2A7K5BTDF is the direct equivalent from TE Connectivity Passive Product. This part maintains identical electrical specifications (7.5 kOhms ±0.1%, 0.1W) and mechanical dimensions. The primary difference is packaging format (Tape & Reel versus unspecified for main part) and ROHS3 compliance certification. This substitute is suitable for direct replacement in all applications where the main part is specified.

Upgraded Performance (Enhanced Tolerance): ERA-6ARB752V and ERA-6ARW752V from Panasonic Electronic Components offer increased power rating (0.125W versus 0.1W) and ROHS3 compliance. ERA-6ARW752V provides tighter tolerance (±0.05% versus ±0.1%), making it suitable for applications requiring enhanced precision. Both parts include AEC-Q200 automotive qualification, appropriate for automotive and high-reliability applications.

Maximum Performance Upgrade (Tightest Tolerance + Anti-Sulfur): RG2012N-752-W-T1 from Susumu combines the tightest tolerance (±0.05%), highest power rating (0.125W), AEC-Q200 automotive qualification, and anti-sulfur protection. The reduced seated height (0.020" versus 0.026") provides additional design flexibility for space-constrained applications. This part is suitable for demanding automotive, industrial, and high-reliability environments.

Product Status Consideration: All substitute parts maintain Active product status, ensuring continued availability and manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can RN73C2A7K5BTDF be used as a direct replacement for 1676437-5?

A: Yes. RN73C2A7K5BTDF is the direct equivalent from TE Connectivity Passive Product with identical electrical specifications (7.5 kOhms ±0.1%, 0.1W, 0805 package). The parts are functionally interchangeable. Packaging format differs (Tape & Reel), but this does not affect circuit performance.

Q: What is the advantage of using ERA-6ARB752V or ERA-6ARW752V over the main part?

A: Both Panasonic parts offer increased power rating (0.125W versus 0.1W), providing additional thermal margin. ERA-6ARW752V additionally provides tighter tolerance (±0.05% versus ±0.1%) for precision-critical circuits. Both include ROHS3 compliance and AEC-Q200 automotive qualification, suitable for regulated industries and automotive applications.

Q: Is RG2012N-752-W-T1 compatible with the original 1676437-5 footprint?

A: Yes. RG2012N-752-W-T1 maintains the 0805 (2012 Metric) package with identical length and width (0.079" x 0.049"). The seated height is reduced to 0.020" (versus 0.026" for the main part), which is compatible with standard PCB layouts and may provide additional clearance in space-constrained designs.

Q: Can I use a substitute part with tighter tolerance (±0.05%) in place of ±0.1% specification?

A: Yes. Tighter tolerance is a compatible upgrade. Parts with ±0.05% tolerance (ERA-6ARW752V, RG2012N-752-W-T1) meet or exceed the ±0.1% requirement and are suitable for direct substitution in any application specifying the main part.

Q: Are the substitute parts suitable for automotive applications?

A: ERA-6ARB752V, ERA-6ARW752V, and RG2012N-752-W-T1 include AEC-Q200 automotive qualification. The main part 1676437-5 does not specify automotive qualification. For automotive applications, the Panasonic or Susumu substitutes are recommended.

Q: What is the difference between ERA-6ARB752V and ERA-6ARW752V?

A: Both parts are Panasonic ERA-6A series with identical power rating (0.125W) and AEC-Q200 qualification. The primary difference is tolerance: ERA-6ARB752V is ±0.1%, while ERA-6ARW752V is ±0.05%. Select ERA-6ARW752V for applications requiring tighter tolerance control.

Q: Does RG2012N-752-W-T1 anti-sulfur feature provide additional protection?

A: Yes. The anti-sulfur feature protects against sulfur-induced corrosion in harsh environments. This is beneficial for applications exposed to industrial pollutants, high-humidity conditions, or corrosive atmospheres. Standard parts without this feature are suitable for controlled environments.

Q: Can all substitute parts be used in Tape & Reel packaging?

A: Yes. All identified substitute parts are available in Tape & Reel (TR) packaging format, suitable for automated assembly processes and high-volume production.
