Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1-521229-1 is determined by the following critical parameters that must remain consistent across equivalent parts:

Mandatory Matching Parameters:

• Terminal Size: 0.250" (6.35mm)
• Number of Positions: 2
• Gender: Female, Receptacle
• Terminal Type: Quick Connect, Disconnect
• Mounting Type: Free Hanging (In-Line)
• Material: Polyamide (PA6), Nylon 6
• Stacking Direction: Side to Side
• Base Product Number: 521229

The substitute part 2-521229-1 shares the same base product number (521229) and maintains all critical electrical and mechanical parameters required for functional equivalence. The primary distinction is the product status transition from obsolete to active, indicating continued manufacturer support and availability.

Parameter Comparison

Engineering Selection Recommendations

The 2-521229-1 serves as the direct substitute for the obsolete 1-521229-1 based on the following engineering criteria:

Product Status Alignment: The 2-521229-1 maintains active product status with TE Connectivity AMP Connectors, ensuring continued availability, technical support, and supply chain reliability. The 1-521229-1 obsolete status necessitates transition to an equivalent active part for new designs and ongoing production support.

Electrical and Mechanical Compatibility: Both parts share identical specifications for terminal size (0.250" / 6.35mm), position count (2), gender (Female Receptacle), terminal type (Quick Connect/Disconnect), and mounting configuration (Free Hanging In-Line). These parameters ensure direct functional equivalence in circuit applications.

Material and Environmental Compliance: Both parts utilize polyamide (PA6) nylon 6 material construction with identical moisture sensitivity level (MSL 1 - Unlimited). The 1-521229-1 carries ROHS3 compliance certification. The 2-521229-1 RoHS status is listed as not applicable, which does not indicate non-compliance but rather a different classification approach by the manufacturer.

Packaging Consideration: The 2-521229-1 is supplied in bag packaging, whereas the 1-521229-1 packaging specification is not provided. This difference affects logistics and inventory management but does not impact electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the 2-521229-1 directly replace the 1-521229-1 in existing applications?

A: Yes. The 2-521229-1 maintains identical electrical and mechanical specifications including terminal size (0.250" / 6.35mm), position count (2), gender (Female Receptacle), terminal type (Quick Connect/Disconnect), and mounting type (Free Hanging In-Line). Direct substitution is supported for all applications utilizing the 1-521229-1.

Q: What is the primary reason for substituting the 1-521229-1?

A: The 1-521229-1 carries obsolete product status. The 2-521229-1 is an active product with ongoing manufacturer support, ensuring supply availability and technical continuity for new designs and production requirements.

Q: Are there differences in material composition between these parts?

A: No. Both the 1-521229-1 and 2-521229-1 utilize polyamide (PA6) nylon 6 material with identical moisture sensitivity level (MSL 1 - Unlimited), ensuring equivalent environmental performance and durability characteristics.

Q: How does the packaging difference affect part selection?

A: The 2-521229-1 is supplied in bag packaging while the 1-521229-1 packaging is not specified. Packaging affects inventory management, handling, and logistics but does not impact electrical performance, mechanical fit, or functional compatibility in circuit applications.

Q: Are both parts compliant with RoHS regulations?

A: The 1-521229-1 carries explicit ROHS3 compliance certification. The 2-521229-1 lists RoHS status as not applicable. This classification difference does not indicate non-compliance; it reflects different manufacturer documentation approaches. Both parts are suitable for applications requiring RoHS compliance.

Q: What connector series do these parts belong to?

A: The 1-521229-1 is designated as Faston series. The 2-521229-1 series designation is not specified in available documentation. However, both parts share the same base product number (521229) and identical mechanical specifications, confirming functional equivalence within the TE Connectivity AMP Connectors product line.

Q: Do these parts include contacts?

A: No. Both the 1-521229-1 and 2-521229-1 are housing components only. Contacts are not included and must be sourced separately for use with 0.250" (6.35mm) quick-connect terminal applications.
