Substitute Part Grouping Explanation

The ASRM2JT100R and ASRM2JA100R are parametric equivalents within the Stackpole ASRM series. Both parts share identical electrical specifications: 100 Ohms resistance, ±5% tolerance, and 2W power rating. Both are metal film axial resistors with identical physical dimensions (5.00mm x 15.00mm), operating temperature range (-55°C ~ 155°C), and feature set (flame retardant coating, pulse withstanding, safety certification).

The substitution is valid based on the following key parameters:

• Resistance value and tolerance
• Power rating
• Composition and construction type
• Physical dimensions
• Operating temperature range
• Compliance certifications (ROHS3, REACH Unaffected)

The only difference between these parts is the packaging format: ASRM2JT100R is supplied in Tape & Reel (TR) format, while ASRM2JA100R is supplied in Cut Tape (CT) format. Both formats contain identical components suitable for equivalent circuit performance.

Parameter Comparison

Engineering Selection Recommendations

Both ASRM2JT100R and ASRM2JA100R are active production parts from Stackpole Electronics Inc with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on packaging requirements for your assembly process. Tape & Reel (TR) format is suitable for automated pick-and-place assembly operations, while Cut Tape (CT) format is appropriate for manual assembly or lower-volume applications. Both parts maintain identical electrical performance and thermal characteristics across the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can ASRM2JA100R be used as a direct replacement for ASRM2JT100R?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, power rating, physical dimensions, and operating characteristics. The difference is packaging format only.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) format supplies components on continuous carrier tape wound on a reel, optimized for automated assembly equipment. Cut Tape (CT) format supplies components on cut segments of carrier tape, suitable for manual handling or lower-volume assembly processes.

Q: Are both parts RoHS compliant?

A: Yes. Both ASRM2JT100R and ASRM2JA100R are ROHS3 compliant and REACH unaffected.

Q: Do these resistors have the same temperature coefficient?

A: Yes. Both parts have a temperature coefficient of 0 / -1800ppm/°C and operate across the identical temperature range of -55°C to 155°C.

Q: Can I mix packaging formats in the same assembly?

A: Yes. Since both parts are electrically and mechanically identical, they can be used interchangeably in the same circuit design. Packaging format selection depends on your assembly process requirements.
