Substitute Part Grouping Explanation

The AH173-PG-A-A qualifies as a direct substitute for the AH173-PL-A-A based on identical electrical and mechanical specifications. Substitution is valid when the following parameters match exactly:

• Hall Effect technology with South Pole polarization
• Identical sensing range: 6mT trip threshold and -6mT release threshold
• Matching supply voltage range: 3V ~ 20V
• Identical current specifications: 6mA maximum supply current and 25mA maximum output current
• Open collector output configuration
• Identical operating temperature range: -40°C ~ 125°C
• Through hole mounting in 3-SIP package with formed leads
• ROHS3 compliance and MSL 1 rating

The primary distinction is product status: AH173-PL-A-A is obsolete while AH173-PG-A-A is active, with packaging differentiation (Tape & Box for the substitute versus unspecified for the original).

Parameter Comparison

Engineering Selection Recommendations

The AH173-PG-A-A is the appropriate substitute for the obsolete AH173-PL-A-A. Both components maintain identical electrical performance characteristics and mechanical compatibility. The substitute part carries active product status, ensuring continued availability and manufacturer support. Both parts satisfy ROHS3 compliance requirements and carry equivalent environmental certifications (REACH Unaffected, EAR99 classification). The packaging difference (Tape & Box format for the substitute) does not affect functional compatibility in through-hole applications. Selection of the AH173-PG-A-A eliminates obsolescence risk while preserving complete design compatibility.

Frequently Asked Questions (FAQ)

Q: Can AH173-PG-A-A directly replace AH173-PL-A-A in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The 3-SIP through-hole package, pinout, and all electrical specifications match exactly. No circuit modifications are required.

Q: What is the primary reason for substitution?

A: The AH173-PL-A-A is classified as obsolete. The AH173-PG-A-A is the active equivalent, ensuring long-term component availability and manufacturer support.

Q: Are there differences in sensing performance between these parts?

A: No. Both components feature identical Hall Effect technology with South Pole polarization, 6mT trip threshold, and -6mT release threshold. Sensing range and response characteristics are equivalent.

Q: Does the Tape & Box packaging of the substitute affect compatibility?

A: No. Packaging format applies only to supply and handling. The component itself, its pinout, and electrical characteristics remain unchanged. Through-hole mounting compatibility is preserved.

Q: Are compliance certifications identical?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99. MSL rating is 1 (Unlimited) for both components.

Q: What is the operating temperature range for both parts?

A: Both the AH173-PL-A-A and AH173-PG-A-A operate across -40°C to 125°C (TA), providing identical thermal performance specifications.
