Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 521112-1 is determined by strict alignment of the following critical parameters:

• Tab Width: 0.250" (6.35mm) — ensures mechanical fit with mating connectors
• Wire Gauge: 14-18 AWG — maintains electrical and thermal performance characteristics
• Terminal Type: Angled - 90°, Flag — preserves mechanical orientation and mounting configuration
• Gender: Female — ensures correct mating polarity
• Insulation: Fully Insulated — maintains electrical safety and isolation properties
• Termination Method: Crimp — confirms wire attachment compatibility
• Mounting Type: Free Hanging (In-Line) — preserves installation methodology
• Contact Material: Brass — maintains electrical conductivity and corrosion resistance baseline

The substitute part 1969109-2 satisfies all critical parameters listed above, making it functionally equivalent for direct substitution in applications requiring the 521112-1 connector.

Parameter Comparison

Engineering Selection Recommendations

The 1969109-2 connector is the direct equivalent substitute for the obsolete 521112-1 part number. Both connectors meet ROHS3 compliance requirements and carry identical Moisture Sensitivity Level (MSL) ratings of 1 (Unlimited), indicating no special handling or storage constraints.

The primary distinction between the two parts is product status: the 521112-1 is obsolete, while the 1969109-2 is an active product currently manufactured and stocked. The 1969109-2 features a tin contact finish and white insulation color, compared to the natural color of the 521112-1. These cosmetic and finish differences do not affect electrical or mechanical performance in applications requiring the specified 0.250" tab width, 14-18 AWG wire gauge, and 90° angled flag terminal configuration.

Both parts carry identical export classification (EAR99) and harmonized tariff codes (8536.90.4000), confirming regulatory equivalence for procurement and logistics purposes.

Frequently Asked Questions (FAQ)

Q: Can the 1969109-2 be used as a direct replacement for the 521112-1 in existing designs?

A: Yes. The 1969109-2 satisfies all critical electrical and mechanical parameters: identical tab width (0.250"), wire gauge (14-18 AWG), terminal type (90° angled flag), gender (female), insulation type (fully insulated), termination method (crimp), and mounting configuration (free hanging in-line). The connector is functionally equivalent for direct substitution.

Q: What is the difference in color between the two parts?

A: The 521112-1 features natural-colored insulation, while the 1969109-2 features white insulation. This is a cosmetic difference and does not affect electrical performance or mechanical compatibility.

Q: Does the tin contact finish on the 1969109-2 affect compatibility?

A: No. The tin contact finish on the 1969109-2 is a surface treatment applied to the brass contact material. Both parts use brass as the base contact material. The tin finish enhances corrosion resistance and does not compromise electrical or mechanical compatibility with mating connectors designed for the 0.250" tab width specification.

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

A: No. Both the 521112-1 and 1969109-2 are ROHS3 compliant, carry identical MSL ratings (1 - Unlimited), and share the same export classification (EAR99) and harmonized tariff code (8536.90.4000).

Q: Why is the 521112-1 listed as obsolete?

A: The 521112-1 has been discontinued by TE Connectivity AMP Connectors. The 1969109-2 is the active equivalent product currently manufactured and available for procurement.

Q: What packaging is available for the 1969109-2?

A: The 1969109-2 is supplied in bulk packaging, with 849 pieces currently in stock as new original inventory.
