Key Parameters

Substitute Part Grouping Explanation

The substitute part 1982890000 qualifies as a direct equivalent based on the following critical parameters:

• Electrical Compatibility: Identical current rating (24A IEC, 18.5A UL) and voltage rating (400V IEC, 300V UL)
• Mechanical Compatibility: Matching pitch (5.08mm), position count (2), mounting type (free hanging in-line), and wire entry angle (270°)
• Termination Compatibility: Identical termination style (screwless leg spring, push-in spring) and wire gauge acceptance (12-26 AWG / 0.2-2.5mm²)
• Environmental Compatibility: Matching operating temperature range (-50°C ~ 100°C), contact material (copper alloy), and housing material (PBT)
• Compliance Alignment: Both parts maintain UL94 V-0 flammability rating, RoHS compliance, and REACH unaffected status

The primary distinction is product status: 1982120000 is obsolete, while 1982890000 is active. Housing color differs (black vs. orange) but does not affect electrical or mechanical function.

Parameter Comparison

Engineering Selection Recommendations

Part 1982890000 is the direct active equivalent for obsolete part 1982120000. Selection is based on:

• Compliance Continuity: Both parts maintain identical UL94 V-0 flammability certification, RoHS compliance, and REACH unaffected status, ensuring regulatory alignment across product lifecycles.
• Electrical Equivalence: Matching current and voltage ratings under both IEC and UL standards guarantee interchangeability in circuit applications without derating or redesign.
• Mechanical Interchangeability: Identical pitch, position count, mounting configuration, and wire entry angle ensure direct mechanical fit within existing connector systems.
• Active Product Status: Part 1982890000 is currently in active production with confirmed inventory availability (904 pcs), providing supply chain continuity for ongoing procurement.

The housing color difference (black to orange) is a cosmetic variation that does not affect electrical performance or mechanical function. Selection between these parts should be based on supply availability and any application-specific color coding requirements.

Frequently Asked Questions (FAQ)

Q: Can 1982890000 replace 1982120000 in existing assemblies?

A: Yes. All electrical, mechanical, and environmental parameters are identical. The parts are functionally interchangeable. Housing color is the only difference and does not affect performance.

Q: What determines substitution eligibility for this terminal block plug?

A: Substitution is valid when the following parameters match: pitch (5.08mm), position count (2), connector type (plug with female sockets), mounting type (free hanging in-line), wire entry angle (270°), current rating (24A IEC / 18.5A UL), voltage rating (400V IEC / 300V UL), wire gauge acceptance (12-26 AWG), termination style (screwless leg spring), and operating temperature range (-50°C to 100°C).

Q: Why is 1982120000 listed as obsolete?

A: Product status reflects manufacturer lifecycle decisions. Obsolete designation indicates the part is no longer in active production. Part 1982890000 provides functional continuity for applications requiring this connector type.

Q: Does the housing color change affect circuit performance?

A: No. Housing color is a cosmetic attribute. Electrical performance, mechanical fit, and environmental ratings remain unchanged. Color selection may be relevant only for application-specific identification or color-coding schemes.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both 1982120000 and 1982890000 are RoHS compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the wire gauge compatibility range?

A: Both parts accept wire gauges from 12 to 26 AWG, equivalent to 0.2 to 2.5mm². This range accommodates standard industrial wiring applications.

Q: What packaging is available for part 1982890000?

A: Part 1982890000 is supplied in box packaging. Inventory availability is 904 pieces of new original stock.
