Substitute Part Grouping Explanation

Substitution of the RGH1608-2C-P-112-B is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Resistance value: 1.1 kOhms
• Tolerance: ±0.1%
• Package / Case: 0603 (1608 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±25ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Secondary Consideration:

• Power Rating: Substitute parts may operate at equal or lower power ratings (0.1W or 0.167W) provided all other electrical and mechanical parameters remain equivalent

Two substitute parts meet these criteria with full electrical and mechanical compatibility to the main part number.

Engineering Selection Recommendations

RG1608P-112-B-T5 (Susumu)

This substitute is manufactured by Susumu, the original manufacturer of the RGH1608-2C-P-112-B. The RG1608P-112-B-T5 maintains full electrical equivalence across resistance, tolerance, temperature coefficient, and operating temperature range. The power rating is reduced from 0.167W to 0.1W; this substitution is valid for applications where the circuit design does not require the full 0.167W dissipation capability. The part includes Anti-Sulfur treatment and AEC-Q200 automotive qualification, providing enhanced reliability for demanding environments. Product status is Active with 5465 units in stock. Packaging is Tape & Reel (TR).

RP73PF1J1K1BTDF (TE Connectivity Passive Product)

This substitute is manufactured by TE Connectivity under the RP73 series (Holsworthy production line). The RP73PF1J1K1BTDF provides exact electrical equivalence to the main part, including identical 0.167W power rating, 1.1 kOhms resistance, ±0.1% tolerance, and ±25ppm/°C temperature coefficient. Physical dimensions show minor variation in length (0.061" vs 0.063") and height (0.022" vs 0.020"), remaining within standard PCB assembly tolerances. Product status is Active with 3494 units in stock. Packaging is Tape & Reel (TR). REACH status is listed as Vendor Undefined.

Both substitutes are ROHS3 compliant with MSL 1 rating and maintain full compatibility with the original part's electrical performance and thermal operating range.

Frequently Asked Questions (FAQ)

Q: Can RG1608P-112-B-T5 be used as a direct replacement for RGH1608-2C-P-112-B?

A: Yes, with power dissipation consideration. The RG1608P-112-B-T5 is electrically equivalent across all critical parameters: 1.1 kOhms ±0.1%, ±25ppm/°C temperature coefficient, and -55°C to 155°C operating range. The power rating is 0.1W versus the original 0.167W. Substitution is valid if circuit power dissipation does not exceed 0.1W at the resistor location.

Q: What are the physical differences between RP73PF1J1K1BTDF and RGH1608-2C-P-112-B?

A: Both components use the 0603 (1608 Metric) package. The RP73PF1J1K1BTDF has a length of 0.061" (1.55mm) compared to 0.063" (1.60mm) for the main part, and a maximum seated height of 0.022" (0.55mm) versus 0.020" (0.50mm). These dimensional variations are within standard PCB assembly and reflow tolerances and do not affect functional compatibility.

Q: Are both substitute parts available in the same packaging format?

A: Both RG1608P-112-B-T5 and RP73PF1J1K1BTDF are supplied in Tape & Reel (TR) packaging. The original RGH1608-2C-P-112-B packaging format is not specified in the provided data.

Q: Which substitute should be selected for automotive applications?

A: The RG1608P-112-B-T5 carries AEC-Q200 automotive qualification and Anti-Sulfur treatment, making it the preferred choice for automotive environments. The RP73PF1J1K1BTDF does not list automotive qualification in the provided specifications.

Q: What is the impact of the power rating difference between RG1608P-112-B-T5 (0.1W) and the original part (0.167W)?

A: The lower power rating of RG1608P-112-B-T5 restricts its use to applications where resistor power dissipation remains below 0.1W. If the circuit design requires dissipation capability above 0.1W, the RP73PF1J1K1BTDF with 0.167W rating is the appropriate substitute.

Q: Are there compliance or regulatory differences between the substitutes?

A: Both substitutes are ROHS3 compliant with MSL 1 rating. The RG1608P-112-B-T5 is REACH Unaffected. The RP73PF1J1K1BTDF lists REACH status as Vendor Undefined. For applications requiring confirmed REACH compliance, the RG1608P-112-B-T5 is the specified choice.
