PM124SH-680M-RC Equivalent & Substitute Parts

Part Overview

The PM124SH-680M-RC is a 68 µH shielded drum core wirewound inductor manufactured by Bourns Inc., rated for 1.5 A continuous current with a maximum DC resistance of 200 mOhm. This surface mount component is designed for applications requiring controlled inductance with electromagnetic shielding in compact form factors. The part maintains active product status with full RoHS3 compliance and unlimited moisture sensitivity rating, making it suitable for industrial and commercial electronic assemblies operating across the -40°C to 125°C temperature range.

Alternative models become necessary when primary part availability is constrained, supply chain disruptions occur, or design flexibility is required while maintaining identical electrical and mechanical performance specifications.

Substitute Part Grouping Explanation

The SRR1240-680M qualifies as a direct substitute for the PM124SH-680M-RC based on strict electrical and mechanical parameter equivalence. Substitution is valid when the following criteria are met:

• Inductance value: 68 µH (identical)
• Current rating: 1.5 A (identical)
• DC resistance: 200 mOhm maximum (identical)
• Shielding configuration: Shielded (identical)
• Core material: Ferrite (identical)
• Inductance tolerance: ±20% (identical)
• Operating temperature range: -40°C to 125°C (identical)
• Package dimensions: 12.50mm x 12.50mm x 4.50mm (identical)
• Mounting technology: Surface mount, tape and reel packaging (identical)
• Compliance certifications: RoHS3 compliant, REACH unaffected (identical)

Both parts are manufactured by Bourns Inc. and maintain active product status, ensuring long-term availability and supply chain reliability.

Parameter Comparison

Engineering Selection Recommendations

Both PM124SH-680M-RC and SRR1240-680M are active products with identical electrical specifications, mechanical dimensions, and regulatory compliance certifications. Selection between these parts should be based on availability and supply chain considerations rather than technical performance differences.

The SRR1240-680M currently maintains higher inventory levels (3482 pieces) compared to the PM124SH-680M-RC (663 pieces), making it the preferred choice for applications where supply continuity is a priority. Both parts satisfy RoHS3 compliance requirements and REACH regulatory obligations, ensuring compatibility with current environmental standards for electronic component manufacturing and assembly.

Frequently Asked Questions (FAQ)

Q: Can SRR1240-680M be used as a direct replacement for PM124SH-680M-RC in existing designs?

A: Yes. Both inductors share identical electrical parameters (68 µH inductance, 1.5 A rating, 200 mOhm DCR), mechanical dimensions (12.50mm x 12.50mm x 4.50mm), and surface mount packaging. No circuit modifications or PCB layout changes are required.

Q: Are there differences in shielding effectiveness between these two models?

A: Both parts are specified as shielded ferrite drum core inductors with identical Q factor (19 @ 2.52 MHz) and self-resonant frequency (11 MHz). No performance difference in electromagnetic shielding is indicated by the provided specifications.

Q: What is the significance of the different base product numbers (PM124SH vs. SRR1240)?

A: The base product numbers identify different series within Bourns Inc.'s inductor portfolio. Despite different series designations, these parts are electrically and mechanically equivalent for the 68 µH, 1.5 A configuration specified.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both PM124SH-680M-RC and SRR1240-680M carry MSL Level 1 (Unlimited), indicating no moisture sensitivity constraints during storage, handling, or assembly processes.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts maintain identical RoHS3 compliance status and REACH unaffected classification, meeting current regulatory requirements for industrial and commercial electronic applications.

Q: What is the operating temperature range for both inductors?

A: Both parts operate across the -40°C to 125°C temperature range, suitable for industrial environments and applications requiring extended thermal performance.
