Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters:

Critical Electrical Parameters:

• Resistance value: 78.7 kOhms
• Tolerance: ±0.1%
• Temperature coefficient: ±25ppm/°C
• Composition: Thin Film

Critical Mechanical Parameters:

• Package / Case: 0402 (1005 Metric)
• Number of terminations: 2
• Physical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm)

Compliance & Environmental:

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• Operating temperature range compatibility

All identified substitute parts maintain these core specifications. Variations in power rating, height, and specific feature sets (anti-sulfur, AEC-Q200 ratings) are noted but do not disqualify substitution when electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Full Equivalence):

ERA-2AEB7872X (Panasonic) and RG1005P-7872-B-T5 (Susumu) are functionally equivalent. Both maintain identical electrical specifications, identical power rating, identical operating temperature range, and both carry AEC-Q200 automotive qualification. Physical height is identical at 0.016" (0.40mm). Selection between these two is based on inventory availability and supply chain requirements.

Secondary Substitutes (Electrical Equivalence with Variations):

CPF0402B78K7E1 (TE Connectivity) and RT0402BRD0778K7L (YAGEO) maintain all critical electrical parameters and operating temperature range. Both are 0.063W rated. Physical height is reduced to 0.014" (0.35mm), which may be advantageous in space-constrained layouts. Neither carries AEC-Q200 certification. These substitutes are suitable for non-automotive applications or where automotive qualification is not required.

Extended Operating Temperature Substitute:

TNPW040278K7BEED (Vishay Dale) provides extended operating temperature range to 175°C (versus 155°C for the main part) and higher power rating at 0.13W. This part carries AEC-Q200 certification and anti-sulfur coating. The increased power rating and temperature range make this suitable for applications requiring enhanced thermal performance.

All substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the main part specifications.

Frequently Asked Questions (FAQ)

Q: Can CPF0402B78K7E1 be used as a direct replacement for RG1005P-7872-B-T5?

A: CPF0402B78K7E1 is electrically equivalent with identical resistance, tolerance, temperature coefficient, and power rating. The primary difference is the absence of AEC-Q200 automotive certification. If automotive qualification is not a design requirement, this part is a valid substitute. Physical height is 0.014" versus 0.016", which may affect PCB layout in height-constrained applications.

Q: What is the difference between the 0.063W and 0.13W power ratings?

A: Power rating indicates maximum continuous power dissipation. TNPW040278K7BEED is rated for 0.13W versus 0.063W for the main part. The higher rating provides additional thermal margin and is suitable for applications with higher current or voltage stress. The 0.13W part can be used in place of the 0.063W part without electrical incompatibility.

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

A: All substitute parts are supplied in Tape & Reel (TR) packaging in 0402 (1005 Metric) case size. Physical dimensions are 0.039" L x 0.020" W (1.00mm x 0.50mm) across all parts. Height variation exists: RG1005P-7872-B-T5, ERA-2AEB7872X, and TNPW040278K7BEED are 0.016" (0.40mm) maximum height, while CPF0402B78K7E1 and RT0402BRD0778K7L are 0.014" (0.35mm) maximum height.

Q: Which substitute part has the highest inventory availability?

A: RT0402BRD0778K7L (YAGEO) has the highest inventory at 26,849 pieces. ERA-2AEB7872X (Panasonic) has 9,978 pieces, TNPW040278K7BEED (Vishay Dale) has 12,083 pieces, and CPF0402B78K7E1 (TE Connectivity) has 2,552 pieces.

Q: Does operating temperature range affect substitution eligibility?

A: Operating temperature range is a critical parameter. The main part operates from -55°C to 155°C. All substitute parts maintain this range or exceed it. TNPW040278K7BEED extends to 175°C, which is compatible with the main part specification. No substitute part has a reduced temperature range.

Q: What does AEC-Q200 certification mean for substitution?

A: AEC-Q200 is an automotive qualification standard. RG1005P-7872-B-T5, ERA-2AEB7872X, and TNPW040278K7BEED carry this certification. CPF0402B78K7E1 and RT0402BRD0778K7L do not. For automotive applications, AEC-Q200 certified parts are required. For industrial or consumer applications, non-certified parts are acceptable.

Q: Can TNPW040278K7BEED replace RG1005P-7872-B-T5 in all applications?

A: TNPW040278K7BEED is a valid substitute with enhanced specifications: higher power rating (0.13W versus 0.063W), extended temperature range (-55°C to 175°C versus -55°C to 155°C), and AEC-Q200 certification. The higher power rating and extended temperature range make it suitable for more demanding applications. No electrical incompatibility exists.
