Grayhill 62M15-L4-PH Rotary Encoder Optical 24PPR Equivalent & Substitute Parts

Part Overview

The Grayhill 62M15-L4-PH is an optical rotary encoder with 24 pulses per revolution (PPR), quadrature incremental output, and 5V supply voltage. This vertical-mount encoder features a 1/4" diameter flatted end actuator, integrated detent mechanism, and built-in switch functionality. The part is mounted via PCB through-hole termination with PC pin connections.

The 62M15-L4-PH maintains Active product status and is ROHS3 compliant with REACH unaffected classification. Substitute parts are identified based on matching electrical specifications, mechanical form factors, and operational parameters that permit direct functional replacement in applications where the primary encoder becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 62M15-L4-PH are classified based on the following substitution criteria:

Primary Substitutes (Full Compatibility): Parts maintaining identical electrical specifications (5V supply, 24 PPR, quadrature output) and mechanical form factors (vertical orientation, 1/4" flatted end actuator, PCB through-hole mounting, PC pin termination, detent, built-in switch).

Secondary Substitutes (Electrical Variation): Parts with matching mechanical and operational characteristics but differing in pulses per revolution (12 PPR or 16 PPR) or supply voltage (3.3V). These parts require application-level verification of resolution and voltage compatibility.

All substitute parts are manufactured by Grayhill Inc., maintain Active product status, and comply with ROHS3 and REACH requirements. Rotational life specification of 1M cycles is consistent across all listed alternatives.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (No Application Modification Required):

The 62R15-02-P and 62S15-M5-P are direct functional equivalents to the 62M15-L4-PH. Both parts maintain identical electrical specifications (5V supply, 24 PPR quadrature output), mechanical configuration (vertical orientation, 1/4" flatted end actuator, PCB through-hole mounting), and operational characteristics (1M cycle rotational life, detent, built-in switch). These parts are suitable for immediate substitution in existing designs without circuit or firmware modification.

Conditional Substitutes (Application-Dependent):

The 62S22-M5-P provides 16 PPR resolution at 5V supply. This part is suitable for applications where lower resolution is acceptable or where the system firmware supports dynamic resolution adjustment. The 62N30-P provides 12 PPR resolution at 5V supply and is applicable only where reduced angular resolution meets system requirements.

The 62V15-02-P maintains 24 PPR resolution but operates at 3.3V supply voltage. This part is suitable only for systems designed for 3.3V logic levels and power supply architecture.

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and Active product status consistent with the primary part.

Frequently Asked Questions (FAQ)

Q: Can the 62R15-02-P replace the 62M15-L4-PH without any circuit modifications?

A: Yes. The 62R15-02-P is electrically and mechanically identical to the 62M15-L4-PH, with matching 5V supply voltage, 24 PPR output, vertical orientation, and PC pin termination. Direct substitution is supported.

Q: What is the difference between the 62S22-M5-P and the 62M15-L4-PH?

A: The 62S22-M5-P provides 16 PPR resolution compared to the 24 PPR of the 62M15-L4-PH. All other electrical and mechanical parameters are identical. The lower resolution may impact angular measurement precision in applications requiring fine position tracking.

Q: Is the 62V15-02-P compatible with a 5V system?

A: No. The 62V15-02-P operates at 3.3V supply voltage and is not compatible with 5V-only systems. Use only in systems with 3.3V power supply and logic level support.

Q: Can the 62N30-P be used as a substitute for the 62M15-L4-PH?

A: The 62N30-P is mechanically and electrically compatible except for resolution. It provides 12 PPR instead of 24 PPR. Substitution is possible only if the application firmware supports lower resolution operation or if reduced angular precision is acceptable.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (62R15-02-P, 62S15-M5-P, 62S22-M5-P, 62N30-P, and 62V15-02-P) are ROHS3 compliant and REACH unaffected, matching the compliance status of the 62M15-L4-PH.

Q: What is the rotational life specification for all these encoders?

A: All parts listed, including the primary 62M15-L4-PH and all substitutes, specify a minimum rotational life of 1M cycles.
