Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity AMP Connectors 1776131-9 are identified based on strict equivalence across the following critical parameters:

Functional Equivalence Criteria:

• Number of Positions: 9 (exact match required)
• Pitch: 0.150" (3.81mm) (exact match required)
• Header Orientation: Vertical (exact match required)
• Type: Header, Male Pins, Shrouded (4 Side) (exact match required)
• Termination Style: Solder (exact match required)
• Mounting Type: Through Hole (exact match required)

Electrical Equivalence Criteria:

• Voltage - UL: 300 V (minimum requirement)
• Current - UL: 8 A or greater (substitute must meet or exceed 8 A minimum; original part rated 11 A)

Mechanical Equivalence Criteria:

• Contact Tail Length: 0.134" (3.40mm) (exact match required)
• Insulation Height: 0.362" (9.20mm) (exact match required)

Compliance Equivalence Criteria:

• Material Flammability Rating: UL94 V-0 (exact match required)
• RoHS Status: RoHS Compliant or equivalent (ROHS3 Compliant acceptable)

The Phoenix Contact 1803497 meets all substitution criteria and is classified as an equivalent substitute part.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The TE Connectivity AMP Connectors 1776131-9 is the specified component and remains the preferred selection when available. This part carries Active product status and is RoHS Compliant. The component is rated for 11 A at 300 V UL specifications and operates across the industrial temperature range of -40°C to 110°C.

Substitute Part Selection: The Phoenix Contact 1803497 is an equivalent substitute when the primary part is unavailable. This substitute maintains functional and mechanical equivalence across all critical parameters including 9-position configuration, 0.150" (3.81mm) pitch, vertical orientation, shrouded male pin header type, solder termination, and through-hole mounting. Both parts achieve UL94 V-0 flammability rating and unlimited moisture sensitivity level (MSL 1).

Electrical Considerations: The Phoenix Contact 1803497 is rated for 8 A at 300 V UL specifications, which is lower than the primary part's 11 A rating. Applications requiring current levels between 8 A and 11 A must be evaluated against the substitute part's electrical specifications. The substitute part also provides IEC ratings of 8 A at 250 V, offering additional compliance documentation.

Material and Compliance Differences: The primary part uses Polyamide (PA) Nylon housing material, while the substitute uses Polybutylene Terephthalate (PBT). Both materials achieve UL94 V-0 flammability rating. The substitute part carries ROHS3 Compliant status and REACH Unaffected designation, providing enhanced compliance documentation compared to the primary part's RoHS Compliant status with Vendor Undefined REACH status.

Physical Appearance: The primary part is black; the substitute part is green. This difference is cosmetic and does not affect electrical or mechanical function.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1803497 be used as a direct replacement for the TE Connectivity 1776131-9?

A: The Phoenix Contact 1803497 is functionally and mechanically equivalent for applications operating at 8 A or below. Both parts share identical pitch (0.150" / 3.81mm), position count (9), orientation (vertical), shrouded male pin header configuration, solder termination, and through-hole mounting. The primary difference is the current rating: the substitute is rated for 8 A versus the original part's 11 A at 300 V UL. Applications requiring current levels above 8 A must use the original TE Connectivity part.

Q: Are there any compatibility issues with PCB mounting?

A: Both parts have identical contact tail length (0.134" / 3.40mm) and insulation height (0.362" / 9.20mm), ensuring compatible PCB footprints. Through-hole mounting specifications are equivalent between both parts.

Q: What is the difference in housing material, and does it affect performance?

A: The TE Connectivity 1776131-9 uses Polyamide (PA) Nylon housing, while the Phoenix Contact 1803497 uses Polybutylene Terephthalate (PBT). Both materials achieve UL94 V-0 flammability rating. The material difference does not affect electrical performance or safety compliance for equivalent operating conditions.

Q: Why is the substitute part rated for lower current?

A: The Phoenix Contact 1803497 is rated for 8 A at 300 V UL, compared to the TE Connectivity part's 11 A rating. This represents a design difference between manufacturers. Applications must be evaluated against the substitute part's 8 A maximum current specification.

Q: Are both parts RoHS compliant?

A: Yes. The TE Connectivity 1776131-9 is RoHS Compliant. The Phoenix Contact 1803497 is ROHS3 Compliant, which represents an updated compliance standard. Both parts meet RoHS requirements.

Q: What is the operating temperature range for the substitute part?

A: The operating temperature range for the Phoenix Contact 1803497 is not specified in the provided data. The TE Connectivity 1776131-9 operates across -40°C to 110°C. Temperature range compatibility must be confirmed with Phoenix Contact technical documentation if operating temperature is a critical design parameter.

Q: Can I use the substitute part in applications requiring IEC compliance?

A: The Phoenix Contact 1803497 provides IEC ratings of 8 A at 250 V, offering documented IEC compliance. The TE Connectivity 1776131-9 does not specify IEC ratings. Applications requiring IEC compliance documentation may benefit from the substitute part's specified IEC parameters.

Q: Does the color difference affect functionality?

A: No. The color difference (black for TE Connectivity, green for Phoenix Contact) is cosmetic and does not affect electrical or mechanical function. Color selection may be relevant only for visual identification or application-specific requirements.

Q: What is the moisture sensitivity level for both parts?

A: Both parts carry Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life and no special moisture control requirements during storage or handling.
