Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 3-2176073-1 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 1.1 kOhms
• Package format: 0201 (0603 Metric)
• Composition: Thin Film
• Number of terminations: 2
• Temperature coefficient: ±25ppm/°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

Allowable Variation Parameters:

• Tolerance: Equal or tighter than ±0.5%
• Power rating: Equal to or greater than 0.03W
• Operating temperature range: Must encompass or match the -55°C ~ 155°C specification

The identified substitute parts meet these criteria while maintaining functional equivalence and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 3-2176073-1 (Primary Part) Select this part when the original specification requires the exact 0.03W power rating and the -55°C ~ 155°C operating temperature range. This component is active and ROHS3 compliant with MSL 1 rating.

Susumu RR0306P-112-D (Direct Substitute) This part provides equivalent electrical performance with identical tolerance (±0.5%) and temperature coefficient (±25ppm/°C). The increased power rating (0.05W) offers thermal margin. The operating temperature range extends to 125°C, which is acceptable for applications not requiring the full 155°C upper limit. ROHS3 compliant with REACH Unaffected status.

Panasonic ERA-1AEB112C (Upgrade Substitute) This part offers superior tolerance specification (±0.1% versus ±0.5%), providing tighter resistance accuracy. Power rating is 0.05W with full -55°C ~ 155°C operating temperature range matching the original specification. ROHS3 compliant with REACH Unaffected status. Select this part when enhanced tolerance performance is required without compromising thermal operating range.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and identical package geometry compatibility with PCB layouts designed for the TE Connectivity 3-2176073-1.

Frequently Asked Questions (FAQ)

Q: Can the Susumu RR0306P-112-D replace the TE Connectivity 3-2176073-1 in all applications?

A: The Susumu RR0306P-112-D is electrically equivalent with matching resistance, tolerance, and temperature coefficient. The primary difference is the reduced upper operating temperature limit (125°C versus 155°C). Substitution is valid for applications where the maximum operating temperature does not exceed 125°C. The increased power rating (0.05W) is compatible with circuits designed for the 0.03W specification.

Q: What is the advantage of the Panasonic ERA-1AEB112C?

A: The Panasonic ERA-1AEB112C provides tighter tolerance (±0.1% versus ±0.5%), resulting in more precise resistance values. It maintains the full -55°C ~ 155°C operating temperature range and increased power rating (0.05W). This part is suitable for applications requiring higher accuracy without thermal operating range compromise.

Q: Are all substitute parts mechanically compatible with the original PCB layout?

A: All substitute parts use the 0201 (0603 Metric) package format. Dimensional variations are minimal: the TE Connectivity part measures 0.023" L x 0.011" W, while substitutes measure 0.024" L x 0.012" W. These differences are within standard PCB pad tolerances and do not require layout modification. Height differences (0.011" versus 0.010" seated maximum) are negligible for standard assembly processes.

Q: Do all parts meet the same compliance requirements?

A: All three parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. Both substitute parts have REACH Unaffected status. All parts carry EAR99 ECCN classification and 8533.21.0030 HTSUS code, ensuring consistent regulatory compliance across substitution options.

Q: Which substitute part should be selected for new designs?

A: For new designs, the Panasonic ERA-1AEB112C is the preferred choice when tolerance performance is a design consideration, as it provides ±0.1% accuracy with full temperature range coverage. The Susumu RR0306P-112-D is suitable when cost optimization is prioritized and the application maximum temperature remains below 125°C.
