Substitute Part Grouping Explanation

The RSMF1JA47R0 has one identified substitute: RSMF1JT47R0. Both parts are manufactured by Stackpole Electronics Inc within the RSMF series and share identical electrical and mechanical specifications. The substitution is valid based on the following matching parameters:

• Resistance value: 47 Ohms
• Tolerance: ±5%
• Power rating: 1W
• Composition: Metal Oxide Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 200°C
• Physical dimensions: 0.126" Dia x 0.354" L (3.20mm x 9.00mm)
• Package case: Axial
• Compliance: ROHS3 Compliant, REACH Unaffected

The primary difference between these parts is packaging configuration: RSMF1JA47R0 is supplied in Tape & Box (TB) format, while RSMF1JT47R0 is supplied in Cut Tape (CT) format.

Parameter Comparison

Engineering Selection Recommendations

Both RSMF1JA47R0 and RSMF1JT47R0 are Active status components with identical electrical performance and physical specifications. Selection between these parts should be based on packaging requirements and inventory availability. The RSMF1JT47R0 offers significantly higher inventory levels (7461 units versus 667 units) and is suitable for applications where Cut Tape packaging is acceptable. Both parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory compatibility for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can RSMF1JT47R0 be used as a direct replacement for RSMF1JA47R0?

A: Yes. Both parts are electrically and mechanically identical with matching resistance, tolerance, power rating, temperature characteristics, and physical dimensions. The difference is packaging format only.

Q: What is the difference between Tape & Box (TB) and Cut Tape (CT) packaging?

A: Tape & Box packaging includes a full reel of components on tape with a protective box. Cut Tape packaging provides components on tape segments without the reel or box. Both formats contain the same component specifications.

Q: Are there any compliance differences between these substitute parts?

A: No. Both parts are ROHS3 compliant and REACH Unaffected, meeting identical regulatory requirements.

Q: Which part should be selected for high-volume production?

A: RSMF1JT47R0 is recommended for high-volume applications due to superior inventory availability (7461 units in stock).

Q: Do these resistors require any special handling or storage considerations?

A: Both parts are metal oxide film axial resistors with identical specifications. Standard component storage practices apply to both packaging formats.
