Key Parameters

Substitute Part Grouping Explanation

Substitution for the ERG-1SJ511 is determined by strict equivalence across the following critical parameters:

• Resistance value: 510 Ohms
• Tolerance: ±5%
• Power rating: 1W
• Composition: Metal Oxide Film
• Package configuration: Axial through-hole
• Features: Flame Proof, Safety characteristics
• Compliance: ROHS3 Compliant

The substitute parts RSMF1JB510R and RSMF1JT510R from Stackpole Electronics Inc meet all these requirements. Both parts maintain identical electrical specifications and physical form factor compatibility. The primary difference between substitutes is packaging format: RSMF1JB510R is supplied in bulk packaging, while RSMF1JT510R is supplied in tape and reel format.

Parameter Comparison

Engineering Selection Recommendations

The ERG-1SJ511 is obsolete and no longer in active production. Both RSMF1JB510R and RSMF1JT510R from Stackpole Electronics Inc are direct functional equivalents with active product status and current manufacturing support.

Selection between the two Stackpole substitutes depends on assembly requirements:

• RSMF1JB510R (bulk packaging) is suitable for manual assembly or low-volume applications
• RSMF1JT510R (tape and reel packaging) is optimized for automated assembly processes

Both parts maintain ROHS3 compliance and are REACH unaffected. The Stackpole substitutes feature improved temperature coefficient stability (±200ppm/°C versus ±350ppm/°C) and are electrically interchangeable within the specified operating parameters.

Physical dimension differences exist: Stackpole parts have a slightly larger diameter (0.126" versus 0.110") while maintaining the same axial length. Verify PCB layout clearance for the increased diameter before final selection.

Frequently Asked Questions (FAQ)

Q: Can RSMF1JB510R and RSMF1JT510R be used interchangeably with ERG-1SJ511?

A: Yes. Both Stackpole parts are electrically and functionally equivalent. The difference is packaging format only. RSMF1JB510R uses bulk packaging; RSMF1JT510R uses tape and reel packaging. Select based on your assembly process requirements.

Q: What is the difference between RSMF1JB510R and RSMF1JT510R?

A: Both parts are identical in electrical specifications and physical dimensions. The only difference is packaging: RSMF1JB510R is supplied in bulk form, while RSMF1JT510R is supplied on tape and reel for automated assembly equipment.

Q: Are there physical dimension differences between ERG-1SJ511 and the Stackpole substitutes?

A: Yes. The ERG-1SJ511 has a diameter of 0.110" (2.80mm), while both Stackpole substitutes have a diameter of 0.126" (3.20mm). The axial length remains 0.354" (9.00mm) for all three parts. Verify PCB layout clearance before substitution.

Q: Do the substitute parts maintain the same compliance certifications?

A: Yes. Both RSMF1JB510R and RSMF1JT510R are ROHS3 compliant and REACH unaffected, matching the ERG-1SJ511 compliance status.

Q: What is the temperature coefficient difference, and does it affect substitution?

A: The ERG-1SJ511 has a temperature coefficient of ±350ppm/°C, while the Stackpole substitutes have ±200ppm/°C. The Stackpole parts offer superior temperature stability. Both operate within the specified temperature range and are suitable for direct substitution.
