ERG-3SJ511 Equivalent & Substitute Parts

Part Overview

The ERG-3SJ511 is a 510 Ohms ±5% 3W through-hole axial resistor manufactured by Panasonic Electronic Components. This metal oxide film resistor features flame-proof and safety characteristics, with an operating temperature range of -55°C to 235°C. The part is currently obsolete, making equivalent substitutes necessary for ongoing production, maintenance, and repair applications. Active alternatives from Stackpole Electronics Inc provide direct functional equivalence while maintaining compliance with current regulatory standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERG-3SJ511 is determined by strict equivalence across the following parameters: resistance value (510 Ohms), tolerance (±5%), power rating (3W), composition (metal oxide film), package type (axial), and operating temperature range (-55°C to 235°C). All substitute parts must maintain ROHS3 compliance and identical electrical specifications.

The substitute parts are grouped into two categories:

Upgrade Substitutes (Direct Equivalents): RSMF3JB510R and RSMF3JT510R from Stackpole Electronics Inc maintain identical electrical parameters and differ only in packaging format (bulk versus tape & reel). Both are active products with improved temperature coefficient performance (±200ppm/°C versus ±300ppm/°C).

Similar Substitute (Dimensional Variation): RSF3JB510R from Stackpole Electronics Inc matches all electrical specifications but features a different physical dimension (0.236" Dia x 0.689" L versus 0.217" Dia x 0.591" L) and uses flame retardant coating instead of flame-proof construction. This part is suitable only when board layout permits the larger form factor.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring direct form-factor compatibility with existing PCB layouts, RSMF3JB510R (bulk packaging) or RSMF3JT510R (tape & reel packaging) are the primary selections. Both parts are active products with ROHS3 compliance and identical dimensional specifications to the obsolete ERG-3SJ511. The choice between bulk and tape & reel packaging depends on procurement and assembly requirements.

RSF3JB510R is suitable as an alternative only when the larger physical dimensions (0.236" Dia x 0.689" L) can be accommodated on the PCB and the flame retardant coating meets application safety requirements. This part maintains electrical equivalence but introduces a dimensional change that requires board layout verification.

All substitute parts maintain the required operating temperature range and electrical specifications for direct functional replacement of the ERG-3SJ511.

Frequently Asked Questions (FAQ)

Q: Can RSMF3JB510R and RSMF3JT510R be used interchangeably with ERG-3SJ511?

A: Yes. Both parts are electrically and dimensionally identical to the ERG-3SJ511. The difference is packaging format: RSMF3JB510R is supplied in bulk, while RSMF3JT510R is supplied in tape & reel. Selection depends on assembly process requirements.

Q: What is the difference between RSMF3JB510R and RSF3JB510R?

A: Both are 510 Ohms ±5% 3W metal oxide film resistors from Stackpole Electronics Inc. The primary differences are physical dimensions (RSMF3JB510R: 5.50mm x 15.00mm; RSF3JB510R: 6.00mm x 17.50mm) and surface treatment (RSMF3JB510R: flame proof; RSF3JB510R: flame retardant coating). RSF3JB510R requires verification that the larger size fits the PCB layout.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RSMF3JB510R, RSMF3JT510R, and RSF3JB510R are all ROHS3 compliant, matching the compliance status of the obsolete ERG-3SJ511.

Q: Does the improved temperature coefficient of substitute parts affect compatibility?

A: No. The substitute parts feature a ±200ppm/°C temperature coefficient compared to the ERG-3SJ511's ±300ppm/°C. This represents improved performance and does not create compatibility issues. Both specifications operate within the same -55°C to 235°C temperature range.

Q: Which substitute should be selected for new designs?

A: RSMF3JB510R or RSMF3JT510R are recommended for new designs. Both are active products with identical electrical and dimensional specifications to the obsolete ERG-3SJ511, ensuring long-term availability and supply chain stability.
