The OJE-SS-124HM,000 meets all substitution criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the OJ-SS-124HM,000 and OJE-SS-124HM,000 are active products from TE Connectivity Potter & Brumfield Relays with identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability. The OJE-SS-124HM,000 currently maintains higher stock levels at 7483 units compared to 1027 units for the OJ-SS-124HM,000. Both parts carry RoHS non-compliant status and are classified under ECCN EAR99. The REACH status differs between the two parts: OJ-SS-124HM,000 is REACH Unaffected while OJE-SS-124HM,000 is Vendor Undefined. For applications requiring REACH compliance documentation, the OJ-SS-124HM,000 provides definitive compliance status.

Frequently Asked Questions (FAQ)

Q: Can the OJE-SS-124HM,000 directly replace the OJ-SS-124HM,000 in existing circuit designs?

A: Yes. The OJE-SS-124HM,000 is a parametric equivalent with identical coil voltage, contact form, current rating, switching voltage, mounting type, termination style, and all timing and operational parameters. Direct substitution is supported without circuit modification.

Q: What are the critical parameters that define substitution eligibility for this relay?

A: Substitution eligibility is determined by matching coil voltage (24VDC), contact form (SPST-NO), current rating (10A), switching voltage (277VAC/30VDC max), mounting type (Through Hole), termination style (PC Pin), coil current (18.8 mA), coil resistance (1.28 kOhms), operating temperature range (-30°C to 70°C), contact material (Silver), seal rating (Sealed - Flux Protection), and timing specifications (10 ms operate, 4 ms release).

Q: Are there differences in compliance certifications between the OJ-SS-124HM,000 and OJE-SS-124HM,000?

A: Both parts are RoHS non-compliant and carry ECCN EAR99 classification. The REACH status differs: OJ-SS-124HM,000 is REACH Unaffected while OJE-SS-124HM,000 is Vendor Undefined. For applications requiring specific REACH compliance documentation, verify the applicable regulatory requirements.

Q: What is the through-hole PC pin termination style used in these relays?

A: PC Pin termination refers to printed circuit board pins designed for insertion into plated through-holes on PCBs. This mounting configuration is standard for both the OJ-SS-124HM,000 and OJE-SS-124HM,000.

Q: How do the inventory levels affect part selection?

A: The OJE-SS-124HM,000 has 7483 units in stock compared to 1027 units for the OJ-SS-124HM,000. For high-volume production requirements, the OJE-SS-124HM,000 may provide better availability. Both parts are active products with ongoing supply.
