Key Parameters

Substitute Part Grouping Explanation

Substitution of terminal connectors is determined by strict equivalence across electrical and mechanical parameters. The primary substitute for 51874-1 is identified as 8-51874-1, which maintains complete compatibility based on the following critical parameters:

Electrical Compatibility Parameters:

• Wire gauge range: 22-26 AWG (identical)
• Contact material: Copper with tin finish (identical)
• Insulation material: Polyamide (PA), Nylon (identical)
• Termination method: Crimp (identical)

Mechanical Compatibility Parameters:

• Terminal type: Flanged (identical)
• Stud/Tab size: 6 Stud (identical)
• Width - Outer Edges: 0.250" (6.35mm) (identical)
• Length - Overall: 0.667" (16.94mm) (identical)
• Mounting type: Free Hanging (In-Line) (identical)
• Insulation diameter: 0.050" ~ 0.082" (1.27mm ~ 2.08mm) (identical)
• Tongue inside opening: 0.145" (3.68mm) (identical)

Regulatory Compliance Parameters:

• RoHS Status: RoHS Compliant (both parts)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)
• ECCN: EAR99 (identical)
• HTSUS: 8536.90.4000 (identical)

The substitute part 8-51874-1 differs only in packaging format (Bulk versus Cut Tape) and product status (Active versus Discontinued), with no impact on functional or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 8-51874-1 is a direct functional equivalent to 51874-1 across all electrical and mechanical specifications. Selection of the substitute is supported by the following factors:

Product Status Consideration: The main part 51874-1 is discontinued at DiGi Electronics, creating supply chain constraints. The substitute part 8-51874-1 maintains active product status with higher inventory availability (1521 pieces versus 785 pieces), ensuring continued procurement capability.

Regulatory Compliance: Both parts maintain RoHS compliance and identical regulatory certifications (ECCN: EAR99, HTSUS: 8536.90.4000). The substitute part carries RoHS Compliant designation while the main part carries ROHS3 Compliant designation; both satisfy current regulatory requirements for this component category.

Moisture Sensitivity: Both parts carry MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints for storage, handling, or assembly operations.

Packaging Consideration: The substitute part is supplied in Bulk packaging format rather than Cut Tape. This difference affects order quantities and handling procedures but does not impact component performance or compatibility in assembly applications.

Frequently Asked Questions (FAQ)

Q: Can 8-51874-1 be used as a direct replacement for 51874-1 in existing designs?

A: Yes. The substitute part 8-51874-1 is electrically and mechanically identical to 51874-1 across all specified parameters including wire gauge, terminal dimensions, contact materials, and insulation specifications. No design modifications are required.

Q: What is the difference between the Cut Tape and Bulk packaging formats?

A: Cut Tape (CT) packaging supplies components in individual strips suitable for automated pick-and-place equipment. Bulk packaging supplies components in larger quantities without tape formatting. Both formats contain identical components; packaging selection depends on assembly process requirements and order quantity needs.

Q: Are the RoHS compliance designations equivalent between ROHS3 and RoHS Compliant?

A: Both designations indicate compliance with RoHS regulatory requirements. ROHS3 refers to the third iteration of RoHS regulations. Both parts satisfy current RoHS compliance standards for this component category.

Q: What wire gauges are compatible with these spade terminals?

A: Both 51874-1 and 8-51874-1 are rated for 22-26 AWG wire. The insulation diameter specification of 0.050" ~ 0.082" (1.27mm ~ 2.08mm) defines the compatible wire size range.

Q: Is the serrated termination feature present on both parts?

A: Yes. Both the main part and substitute part include serrated termination as a standard feature, providing consistent wire grip and connection reliability.

Q: What is the stud size specification for these terminals?

A: Both parts feature a 6 stud configuration, which defines the connection point size for mating with corresponding connector housings or terminal blocks.

Q: Are there any storage or handling differences between the two parts?

A: No. Both parts carry identical Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no special storage or handling requirements beyond standard component handling procedures.
